Toshiba C875-S7303 mouse problem with Windows 8

Using Windows 8 all day with my new computer and then the mouse froze. I did the basic reboot and restarts to no avail. When I figured out how to get to the control panel and to the mouse setting I found it had been changed to "other pointing device" not the "snaptics Touchpad V7.2" that it should be. Easy switch, except every time I switched it back it defaults to the "other pointing device". Any suggestions on what is wrong?
